NECK-YOKE.

SPECIFICATION forming part of Letters Patent No. 457,422, dated August11, 1891.

Application filed July 23, 1890. Serial No. 359,588. (No model.)

To all whom it may concern.-

Be it known that I, JOSHUA G. BURBRIDGE, a citizen of the United States,formerly of Neola, Iowa, but now residing at Dubuque, in the county ofDubuque and State of Iowa, have invented certain new and usefulImprovements in Neck-Yokes; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to improvements in neck-yokes;-and my saidinvention consists in certain novel details of construction andoperation of the several parts composing the same, as will behereinafter more specifically described in the specification, andpointed out in the annexed claim.

The object of my invention is to provide a simple connection forlockingthe yoke to the poles of vehicles to prevent the accidentaldisengagement of the yoke from the pole when the same is in use, thatwill be cheap, durable, and effective, and which may be readilymanipulated; and to this end I proceed as follows, reference being hadto the accompanying drawings, forming a part hereof, and in whichdrawings Figures 1 and 2 represent views in perspective and partialsection of a neck-yoke constructed according to my invention, the partsof the same being shown as in their locked or usual position when inuse, and Fig. 3 is a similarview showing the parts as in their respective positions when being unlocked to enable the yoke to be removed fromthe pole. Fig. 4 is a modification.

The letter A indicates the pole, and B the tip thereof, which tip has aflange a, that is placed at an angle relative to said poletip and ismade eccentric therewith or with a wide portion at the under side of thetip that gradually tapers to nothing at the top of said tip, for thepurposes as will presently appear.

0 indicates the yoke, to which is secured by a band 0 that encircles theyoke and has secured between its projecting edges 0' a plate 0 formed atits center into an eye 0 a loop D, that is adapted to fit upon thepole-tip and rest against the flange a, and this loop has at its lowerextremity a hook d, that when the parts are in position, as in Figs. 1and 2, engages beneath the tlange a of the pole-tip and retains the yokein position on the pole.

Any other suitable means for attachment of the hooked loop to the yokemay be employed in place of that shown in Fig. 1such, for instance, thatshown in Fig. 2, where two links are used in connection with the hookedloop, the links being connected to eyes that are secured to the yoke.

To disengage the yoke from the pole, the yoke is simply swung round, soas to bring the hook of the loop upon the top of the poletip coincidentwith the narrow portion of the flange upon said tip, at which point thehook will be outof engagement with the flange and permit the removal ofthe yoke, as shown in Fig.

Instead of having the flange ot' thepole-tip at anacute angle, as shownin Figs. 1, 2, and 3, such flange may be at right angles to saidpole-tip, as shown in Fig. 4; but the construction in Fig. 1 ispreferred.

It will be noted that both the link connection of the hooked loop to theyoke shown in Fig. 2 and the direct connection of said loop with an eyefixed to the yoke permit of a free lateral as well as vertical movementof the yoke with reference to said hooked loop, such a swivel connectionbeing essential to the successful working of the parts.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is

In a neck-yoke, in combination With the pole-tip with flange, the loopfitting upon the pole-tip formed at its lower extremity into a hook thatengages the flange of the pole-tip and at its top into a loop, withaloose flexible connection substantially such as described, between theloop and the yoke, for the purposes specified.

J. G. BURBRIDGE.
